1. Definitions 1/7

Technical approach: Technical textiles are textile materialsand products mainly produced for their technical function and performance; their aesthetic or decorative properties are of secondary importance

Market approach: Technical textiles offer solutions for themanifold technical challenges existing in our society (environmentalprotection, personal safety, general safety, health & well-being)
